  • Patent number: 8152289
    Abstract: A machine, such as a phase change or solid ink printing apparatus, has at least one multiple supply unit in the form of an ink stick disposed therein. The ink stick has an electronically-readable memory device associated therewith, and the memory device has stored therein electronic data related to the ink stick and readable by the machine. The memory device may be attached to the ink stick and removed before the ink stick is used for printing in the machine. In another aspect, the memory device is attached to a container for the ink stick. The container may be a cartridge for use in the machine, or a container for packaging the ink stick. The machine may include a coupler configured to read electronic data from the memory device while the memory device is positioned external to the printing apparatus, thus allowing the machine to verify the suitability of the ink stick before it is installed in the machine.

  • Patent number: 8152155
    Abstract: An envelope feed apparatus comprises a main body having a bottom; top (located opposite the bottom); and sides (located between the bottom and the top). The main body top has a flat surface that supports, for example, a stack of envelopes. The envelope feed apparatus also has a slider that includes sides contacting at least two of the main body sides. The slider sides move in a parallel direction to the main body sides as the slider moves relative to the main body. The slider has at least one roller connected to opposing slider sides. The roller(s) are positioned adjacent the main body top. The roller(s) move in a perpendicular direction to the flat surface of the main body top as the slider moves relative to the main body. The roller(s) contact the stack of envelopes when the stack of envelopes is on the flat surface of the main body top and apply pressure to the stack of envelopes in the perpendicular direction toward the flat surface of the main body top.

  • Patent number: 8152288
    Abstract: A system for use with a phase change ink imaging device comprises a leveler roller disposed along a web path downstream from a printing station. The leveler roller is formed of a thermally conductive material and includes a heater configured to generate thermal energy to heat the leveler roller to a leveling temperature. The leveler roller is positioned to be partially wrapped by the continuous web in order to generate a predetermined dwell time between the continuous web and the leveler roller as the continuous web is being moved. The predetermined dwell time is configured to allow conductive heat transfer to occur between the continuous web and the leveler roller to equalize the continuous web and the melted phase change ink temperatures on the web to within a predetermined range about the leveling temperature. A midheater is disposed along the web path downstream from the leveler roller.

  • Patent number: 8155540
    Abstract: A method and system includes updating an accumulated dispense value from within a toner dispense actuation loop and adjusting the accumulated dispense value by receiving dispense values from at least one control loop element that operates asynchronously from the toner dispense actuation loop. A temporary accumulated dispense value is stored when it is greater than or equal to a predetermined dispense saturation upper limit, or is less than or equal to a predetermined dispense saturation lower limit. An adjusted accumulated dispense value is calculated by subtracting the accumulated dispense value from the temporary accumulated dispense value and multiplying the difference by a predetermined optimized limit gain. A new accumulated dispense value is calculated by adding the adjusted accumulated dispense value to the accumulated dispense value. A toner dispense motor is activated for a time period equal to the on time value, and the on time value is subtracted from the new accumulator value.

  • Patent number: 8154741
    Abstract: A class of add-on system components providing functionality of devices, management of self-help, customization and enhancement of services for devices, and remote monitoring at significantly reduced cost. It reduces the cost of UI and greatly enhances ease-of-use by realizing that the networked system can be headless and use a browser-based UI for its platform. It embeds a Device Model Agent (DMA) and connects to the Device-Centric Services platform to offer services. Additionally, it offers customized diagnostic access for customer representatives to enable self-help service actions to be performed, unifies and manages multiple access needs to several disparate data access mechanisms, and uses largely COTS PC hardware rather than customized PWBs.
